HINGE CONSTRUCTION FOR FACE-PLATES AND THE LIKE.

. Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed September 30, 1914. Serial No. 864,197.

To aZZ whom it may concern Be it known that I, WILBERT LUTHER BABGOOK, a citizen of the United States, residing at i/Vaterbury, New Haven county, State of Connecticut, have invented certain new and useful Improvements in Hinge Construction for Face-Plates and the like, of which the following is a full, clear, and exact description.

My invention relates to an improved hinge construction for face plates for electrical wall receptacles and the like, the object being to provide a substantial yet economical construction.

In the drawingsFigure l is a front elevation of my completed device, practically full size. Fig. 2 is a rear elevation thereof. Fig. 3 is a section on the line 38 and relatively enlarged. Fig. 4: is a perspective view of a blank used for one of the details. Fig. 5 is a similar view of said finished detail. Fig. 6 is a perspective view of another detail.

1 represents a plate usually of rectangular form and having the offset bevel border 2. Within the field of this plate is an opening which is filled by a swinging door 3, which is hinged to plate 1 by being supported to swing on pivot pins H. The plate 1 is made of comparatively thin yet sufficiently stiff stock to provide the necessary strength without undue waste. The door 3 is preferably struck out from this stock, and is of suitable outline, one end, however, as indicated at 5 being by preference squared, the pivot pins 4-4- entering said end at opposite edges. Since, as I have stated, the plate should be of as thin stock as practicable to save weight and waste material, I have found that adequate pin bearings can not be provided which will withstand the strain and wear of the door 3 unless said pins are very nearly the same diameter as the thickness of the stock used in making the plate and door. To that end I have devised effective means for permitting a relatively heavy pin to be successfully used. In Fig. 4 I have illustrated a door blank. As shown in Fig. 5, I punch into the edges of the door two cavities in line, one of said cavities being seen in said figure. This punch enters at one side of the center line with the result that some of the metal is displaced and forced outwardly to form the ridges 77 at the back of the door plate 8. If a drill were used for forming this cavity, it would not leave enough stock to properly hold a pin of sufiicient size. I, therefore, employ the punching method and actually displace or offset a part of the metal without waste. At the rear of the plate 1, I form two channels in line of approximately a width equal to the diameter of the pins 4l4. I then assemble the parts by inserting the pins 4.4 into the cavities 6, laying the projecting ends of the pins in the aforesaid channels in the back of the plate 1, whereupon the metal adjacent to said channels is displaced as at S8 by appropriate dies so as to partially embrace and yet firmly hold the outer ends of the pins 4l4: against movement in any direction, which pins being in line, constitute a suitable, a strong, and an efi'ective bearing upon which the door 3 may turn. To act as a hinge stop and prevent the door from being pushed entirely through the plate 1, and at the same time to form a recess into which the finger nail or a small tool may be inserted to engage the edge of the door 3 to open it, I strike back a part of the metal of the plate as at 9 (Fig. 1) and incidentally form a shoulder 10 (Fig. 2) against which the rear of the free edge of the hinged door 3 engages when the door is closed.

By this simple construction I may form rapidly and economically hinged plates of the character described from comparatively thin metal without sacrifice to strength or durability.

What I claim is:

1. In a hinge for a plate having a passage therethrough, and a door conformed to said passage and adapted to swing therein, said hinge comprising two pivot pins arranged in line, a cavity in each edge of said door, the metal of said door at the back of said cavity being displaced to form ridges on the back of the door, grooves in the back of said plate at the opposite edges of the passage in said plate, said pins being located in said grooves, a portion of the metal adjacent to said grooves being displaced and overstanding said pins at the back to hold them in place.

2, In a hinge for a plate having a passage therethrough and a door conformed to saidv passage and adapted to swing therein, said hinge comprising two pivot pins ar-- ranged in line, a cavity in each edge of said door, the metal of said door at the back of said cavity being displaced to form ridges on the back of the door, grooves in the back of said plate and at the opposite edges of the passage in said plate, said pins being located in said grooves, and means for holding said 10 H.
